At a place I used to work we were setting up a new raised floor.
The (licensed!) electrician that was setting up the new UPS was
leaning with his hand against one end of the bank of batteries.
He leaned down to tighten the nut on the other end of the bank
of batteries with a metal socket wrench. The UPS was about the
size of four large refrigerators side-by-side, 90% of which was
filled with batteries.

He nearly died and spent quite a long time in the hospital. The
investigation kept the area closed for almost a week.
